According to the Centers for Medicare & Medicaid Services, total federal and state Medicaid spending reached approximately $871.7 billion in the 2023 fiscal year, comprising about 18% of U.S. health care expenditures. This figure represents a significant increase from $613.5 billion in 2019, prior to the onset of the COVID-19 pandemic.
This growth of about 40% in a few years has largely been attributed to greater enrollment and increased service usage during and after the pandemic.
Recent budget legislation enacted during the Trump administration introduced major proposals to restructure federal Medicaid contributions and reduce funding. The “One Big Beautiful Bill Act,” signed into law in 2025, is expected to reduce federal Medicaid expenditures by more than $1 trillion over the next 10 years, while implementing new policies such as work requirements and higher cost-sharing. Some of these provisions may limit funding and coverage for certain beneficiaries, shifting additional costs onto states despite Medicaid’s continued broad reach.
